Urban Building Energy Modelling (UBEM) requires adequate geometrical information to
represent buildings in a 3D digital form. However, open data models usually lack essential …

This paper describes a CityGML Building Interpolation tool (CityBIT) for the creation of user-
defined and interpolated building models for planned and/or existing buildings. A brief …

The present paper describes a semi-automatic process, in which a typical CityGML 3D
building model is enriched with explicit thermal energy related information and stored in a …

Due to the transition from fossil energy carriers to more renewable energy resources, the
availability of energy in future will be fluctuating. Under these conditions, an accurate energy …

Energy supply of buildings in the urban context currently undergoes significant changes. To
consider these changes in the energy systems and the buildings themselves, dynamic …

In this paper, simulations of 500 open-source CityGML building models for heating demand
calculation are presented. Using an archetype-based approach and statistical enrichment …

In the context of growing population and increasing greenhouse gas emissions, urban
energy planning is becoming a topic of high concern. With the rapid pace of urban …

Addressing the gap between available urban building data, energy performance evaluation,
and spatial distribution of end-users is a growing concern of municipalities to support energy …

This paper aims to evaluate the accuracy and strength of a new approach that automatically
calculates the heating demand of whole district areas, modelled in 3D with the open …

At a time when governments are pursuing increasingly ambitious energy efficiency goals,
building energy simulation at the urban scale, combined with the high availability of physical …
